PROCESS OF TREATING PYROXYLINE SCRAPS.

SPECIFICATION forming part of Letters Patent No. 244,916, dated July 26, 1881.

Application filed January 3, i881. (No specimens).

To all whom it may concern:

YBe it known that I, ORLANDO MoNRoE,of Brooklyn, in the county of Kings and State ot' New York, have invented a new and useful Improvement in Processes of Treating Pyroxyline Scraps, of which the following is a specitication, reference being had to the accompanying drawings.

In the manufacture of compounds of vpyroxyline perhaps the most important consideration is the proper admixture and compression 'of the material. The mere grinding of the elements, even though it be so performed as to ei'ectually intermix and blend them, will not insure the eft'ectuation of a good result unless the intermixture be supplemented by a compression of the material, such as will impart to it a suitable degree of even solidit-y. Another highly important consideration is the proper admixture of the coloring agent, particularly where what is known as scrap7 is made use of, and especially where the scrap is composed of pieces or dust of different shades.

To provide a means of accomplishing an effectual mastication and compression of'the compound, as well as a suitable admixture of the coloring agent, are the objects of my invention, which are effected in the manner hereinafter described.

The distinctive novelty of the process consists in rst treating the compound with any appropriate solvent and then subjecting it to the action of a machine whereby it is masticated and compressed, 'the coloring agent being introduced, if desired, before the mastication is attempted.

" In practicing the process, almost any machine may be used which serves to effectually masticate or mix the material, and at the same time to cause it to be properly forced or moved through a mouth or aperture, the mouth or aperture being of such a size as to e'ect the proper compression. Thus, if preferred, a device such as is illustrated in Fig. l, in which A A are mixing-rollers of ordinary construction, and B an attachment in the nature of a nozzle, may be successfully used. The material, being fed in between the rollers A A, is thoroughly mixed or masticated, and being moved through the nozzle or part B, is solidified to form a homogeneous mass of the proper consistency. lf preferred, the part B may be made adjustable by any convenient means,l so that the solidityof the material may be increased or diminished at pleasure, according to circumstances.

lt is quite important, as will be readily understood, that the nozzle or discharge-orifice of the apparatus which is employed in practicing the invention should be of a suitable diameter to accomplish the proper compression or semi-solidiication of the material without causing it to be solidified to an undue extent. If the nozzle beftoo large, the material will be delivered in such form that it will be comparatively valueless, and if the nozzle be too small, great difficulty will be experienced in expelling the material from the machine, and when expelled it will be so nearly solidified that its value will be greatly diminished. The shape of the nozzle will of course be varied according to the objects for which the material is intended to be used.

The machine I prefer to use is shown in Fig. 2,'and consists of a cylinder, Q, which contains a screw or threaded shaft, It, operated in any convenient manner. The cylinder Q is provided with a nozzle or outlet, S, of reduced diameter, through which the material is moved by the rotation of the screw or shaft R. The material having beenreduced, if necessary, to a convenient size to be introdued into the machine, is first treated with a solvent of any ap propriate nature, such as alcohol, wood-Daphtha, 8vo. It' the compound is in what is known as a green state, it will answer to merely dip it in the solvent, permitting it to remain for a few moments, which will cause it to take up a suicient quantity of the solvent to effect the desired result. If it is in the form of lseasoned scrap, it will be immersed in the solvent and permitted to stand for a period of, say, from one to twenty-four hours, more or less, accord ing to circumstances. It will then be introduced into the machine, the machine, by prefer ence, havingbeen heated in anyconvenientway.

If'it be desired to color the material, the coloring agent will be added before the material is introduced into the machine, and, if scrap of different colors is used, will be of such a shade as to cause the resultant material, when completed, tobe of a uniform color.

IOO

I do not claim to be the inventor of the machines which I have described, as they are not new in the arts; but I am the first to discover n method whereby7 they may be made available in the successful treatment ot' compounds of pyroxyline.

What I claim as myinvention, and desire to secure by Letters Patent, is-

1. The process herein described ot' rendering homogeneous com pounds of pyroxyline, which consists n treating the compound with a soivent and then subjecting it to the action of a machine which operates to first mix it and then compress it by forcin it through an outlet or nozzle.

2. The process herein described of rendering movement in processes of treatin g; pyroxyline 2 5 scraps, as above described, I have hereunto set my hand thisr21st dey of March, 1881.
